This disclosure relates to a polymer composition with color pigments highly incorporated, comprising (a) propylene-based copolymers and/or ethylene/C-Calpha-olefin copolymers and (b) one or more color pigments.

Polymer compositions with high color pigments loading

The present invention is related to a composition with about 80 wt % to about 95 wt % of a polymer blend, wherein the polymer blend comprises (a) about 3 wt % to about 25 wt % of a first propylene-based elastomer based on the polymer blend, and (b) about 75 wt % to about 97 wt % of a second propylene-based elastomer based on the polymer blend; and about 5 wt % to about 20 wt % of an ethylene-based polymer; wherein the first propylene-based elastomer and the second propylene-based elastomer each comprise the following: propylene and from about 2 to about 25 wt % units derived from one or more Cor C-Calpha-olefins; triad tacticity greater than about 90% and a heat of fusion less than about 75 J; and wherein the first propylene-based elastomer is different from the second propylene-based elastomer.
